SPECIFICATION forming part of Letters Patent No. 511,326, dated December 26, 1893.

Application iled March 17, 1 89 3.

To all whom it may concern:

Beit known that we, OSCAR A. DE LONG, of New York, county and State of NewYork, and ELEAZER KEMPSHALL, of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Hooks, of which the following is a full, clear, and exact specification.

Our invention relates to improvements in Io hooks, particularly that class of hooks that are used in connection with eyes, the mechanical construction of which is hereinafter fully described.

The object of our invention is to construct I5 a sheet metal hook to be used in connection with a suitable eye. the mechanical arrangement of which hook being such that the accidental disengagement of the hook is almost impossible.

Another obj ect is that this form of hook can be made much cheaper than the hook constructed of wire, inasmuch as it is formed of sheet metal which is cheaper than wire and which can be struck up by means of very sim- 2 5 ple machinery, very rapidly, into a hook fully as good as the wire hook.

Our invention is illustrated by the accompanying drawings, in which- Figure l is a plan View of another form of 3o our invention. Fig. 2 is a vertical cross-section on the plane of theline 2-2 Fig. 3. Fig. 3 shows a plan view of a modification of our invention before the loop or hook is formed, and Fig. lis a side elevation of another modiiication of ourinvention.

A is a sheet metal blank from which the hook is formed. Suitable perforations B B may be formed in one end of the hook to secure it to the garment. To prevent the acci- 4o dental disengagement of the hook from the eye, we out two or more non-intersectin g longitudinal slots in the shank and strike up the entire metal between the said slots to form a rigid raised bend between companion or adjacent slits. This raised portion is formed preferably about midway between the bend forming the hook and the end by which the hook is attached to the garment. The spring Serial No. 466,564. (Nomodel.)

end E of the hook is preferably bent over and down sufficiently far so that the space that intervenes between the said spring end E of the hook and the raised portion D,is so very slight that, for the ordinary eye to pass one way or the other through this narrow space without pressure sufficient to elevate the spring end E of the hook, is impossible.

Fig. 3 illustrates a modication of a hook showing the preferable construction of aheavy hook to be used on heavy garments. In this case, if preferred, ablank may be struck out of the center of the hook to lessen the weight of the hook, and one or more elevations D2 may be struck up between companion slits for the purpose of preventing the accidental disengagement of the hook from the eye, as before described.

Fig. 4 shows another modification in which the hump D3 is formed in the upper, or spring end E, of the hook instead of the lower side of the hook.

We are aware that a sheet metal hook having a raised portion, or a bent tongue, to prevent the disengagement of the hook has been used before, but in all instances one end of this bent tongue hasbeen detached from the blank, s o that when the eye is passed into the hook the unattached end of the tongue is pushed down and is liable to wear into the garment to whichthe hook is attached. In this class of hooks having this bent tongue with one end free, the tongue forms the spring. It is not so in our invention. The spring end E of our hook formsthe spring in everyinstance. For, inasmuch as the elevated or raised portions D, D2, D3, in our invention are all formed as a solid part of, or attached at both ends to, the blank they can aord no spring whatever.

Having thus described our invention, what we claim, and desire to secure by Letters Pat- 9o ent, is-

1. A sheet metal hook consisting of the hook blank A said blank being provided with substantially parallel longitudinal slits, non-intersecting, the entire strip of metal between 95 companion slits being bent or struck upward metal between two or more slits formed in the blank, and with means as described for attaehing the hook to a garment, substantially as and for he purpose specified.
